Question

我创建了一个shapeDrawable border_white.xml：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >
    <corners android:radius="5dp" />
    <stroke
        android:width="2dp"
        android:color="@color/white" />
    <size
        android:width="165dp"
        android:height="40dp" />

    <solid android:color="@android:color/transparent"/>
</shape>

但是当我将其用作背景时，会引发错误：

<TextView
            android:id="@+id/tvCoinFrom"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="@dimen/margin_big"
            android:layout_marginStart="@dimen/margin"
            android:layout_marginLeft="@dimen/margin"
            android:padding="@dimen/padding_small"
            android:textSize="@dimen/text_size_big"
            android:textStyle="bold"
            android:text="BTC"
            android:background="@android:id/background"
            app:layout_constraintBottom_toTopOf="@id/guideline2"
            app:layout_constraintStart_toStartOf="parent"
            style="?style_tv_text_for_primary_color_background"/>

此错误仅在低于21的API中发生，我也在api 27上进行了测试，效果很好。它说错误在于使用该xml作为背景的textview中：

Answer 1

检查是否将shapeDrawable border_white.xml文件保存在drawable-v21目录中，然后将此文件剪切并粘贴到drawable目录中。

ShapeDrawable在低于21的api上不起作用
